The analysis of tire tracks, Lu Chuan had encountered while in school.

However, the course at that time was called vehicle trace analysis.

Tire tracks are a part of it, of course, also the most important part.

In the vast majority of crime scenes, there's always the presence of transport tools.

Take for example the body sinking case at Happy Reservoir, where the killer used an electric scooter to transport the body.

Or the recent case where Chen Yating killed Zhang Zixuan, after dealing with a portion of the body each day, Chen Yating would drive away from the hideout and return home.

In the car's trunk, Lu Chuan and others also detected trace amounts of blood and some small human tissue.

Compared to murder weapons like daggers and hammers, the target of a transport tool is larger and harder to hide.

Therefore, in many cases, tracing the murderer through the transport tools they use is a very important and common method.

In actual case handling, tire track analysis becomes very important in the absence of surveillance.

The tire tracks of a transport tool are like human footprints, possessing uniqueness.

In juridical identification, they can serve as evidence for identifying the same source.

However, this requires a detailed analysis report, not merely a simple image comparison.

For instance, the same tire will leave different tracks on different road surfaces.

Or even under the same road conditions, differences in temperature can result in different tracks.

At the moment of skill card receipt, a vast amount of knowledge and experience related to tire tracks flooded Lu Chuan's mind.

Sitting in the car, Lu Chuan closed his eyes to rest.

Today, it was Yang Sen driving, wanting to experience the driving feel of a decade-old Land Cruiser.

Lu Chuan sat in the front passenger seat, while Old Bai and Liu Guodong chatted in the back.

The topic, of course, was about the case of Zhang Zixuan's murder.

"Old Liu, speaking of the big bone case last time... wasn't it Little Lu and Little Shen who discovered it?"

Chatting along, Old Bai suddenly recalled the case's origin.

Liu Guodong froze for a moment, the driving Yang Sen chimed in, "Yes, yes, these two were on a date, discovered it while eating hotpot."

"This time around, they were also on a date, right? Originally planning to visit an art exhibition?"

Yang Sen's tone rose a bit, patting the resting Lu Chuan: "Little Lu, am I right?"

Lu Chuan, just having finished a system reward acceptance, opened his eyes with some helplessness.

"Brother Yang, we were just having a meal, not on a date."

"Alright then, what's the use of fooling us few folks here."

"Little Shen hasn't gone out for a meal alone with any male colleague besides you in all these years of work."

Old Bai nodded in agreement, "Little Shen is nice, you know her father, right?"

Liu Guodong also nodded, "Our Little Lu is good too, this time should at least merit a commendation."

Speaking of this, a few people looked at Lu Chuan.

Crime Scene Investigation is getting a lot of face time again.

Lately, it seems every time there's a case, Crime Scene Investigation gets some focus.

Lu Chuan isn't too concerned about merit or not.

Getting acknowledged and rewarded is naturally nice, but if not, he wouldn't be able to demand it.

He is currently more concerned about his and Shen Yan's reputation.

These past few days, he has heard some bad rumors.

About him and Shen Yan.

It's not some tabloid news.

In the Criminal Investigation Team, such things are not popular.

Their dates... meals are private matters, and happened only once or twice.

Currently, what circulates in the team is the case of discovering human bones while on a date and discovering human skin at an art exhibition.

There is a bit of a sense of disaster striking wherever they go.

Some young detectives privately call them the death duo.

Meaning, wherever they go, a homicide is bound to occur.

"The case had already happened; we just happened to stumble upon it."

Old Bai raised an eyebrow: "Then why don't others stumble upon it?"

Lu Chuan: "..."

Life sometimes is just like that.

We need to endure its roughness and enjoy the thrill it brings at the same time.

Life is the same, like a rich lady from a big family.

She fears you won't come; she fears you'll behave badly.

Lu Chuan feels he should take Shen Yan to a temple this weekend for a blessing.

Hoo...

He exhales deeply, hoping nothing strange happens at the temple.

It shouldn't, after all, it's a Buddhist sacred place, blessed by Buddha's light; it should be clean, especially now it's a group company.

In the blink of an eye, it's November.

Lu Chuan has been in the Criminal Investigation Team for nearly four months.

The time has been short, but the days have been rather eventful.

The case of Zhang Zixuan's murder has also come to an end.

All evidence and materials are fully prepared.

Chen Yating... barring unexpected developments, probably won't survive.

Speaking of which, it seems in the end, that grassroots artist got the better deal.

He still paints and continues to teach students.

And being under fifty, he's at an age where a man is most charming.

With money, talent, and looks.

He should soon have a third wife and third child.

Chen Yating should have taken Liang Song instead; Zhang Zixuan... her death was somewhat wrongful.

As for the motive for murder, it's actually quite simple.

On September 21st, the day Zhang Zixuan and Liang Song met in the studio, Chen Yating happened to deliver some lotus seed porridge to Liang Song.

She witnessed the entire scene.

Chen Yating had actually suspected Liang Song of having someone else outside.

After all, she rose to her position through similar means back then.

She initially planned to turn a blind eye and live a good life.

But what Chen Yating did not expect was that the place where Zhang Zixuan and Liang Song got intimate was the same bed she used to fool around with Liang Song.

Even the bedding was changed by Chen Yating back in those days.

"They shouldn't have been in the studio... that was my place..."

This was the direct motive for Chen Yating's action.

As for heading to the temple to pray, Lu Chuan and Shen Yan eventually didn't go.

The two, to test if the death duo was really true, deliberately went on two more dates.

However, clearly those two dates were relatively successful.

In the Crime Scene Investigation office, Lu Chuan cleaned everything up early.

At this time, he was tending to the ever more luscious flamingo-lily by the window.

After all this time of care, Lu Chuan found that while watering and fertilizing are important, they're not the most crucial things.

The key is to touch and play with it often.

By doing so, the flamingo-lily has more vibrant colors, and its leaves are more moist.

Old Bai and Yang Sen, as always, stepped into the office right on time.

Picking up the prepared enamel mug of tea, Old Bai cleared his throat and started singing a tune.

The tone was rich, with a touch of someone nearing retirement.

"Old Liu gone to a meeting?"

Lu Chuan nodded: "Today's a big morning meeting, probably will last till noon."

The Criminal Investigation Team has had quite a relaxed time recently.

With the end of Zhang Zixuan's human skin case, everyone could finally sigh in relief.

Those who needed a vacation took one, and those who needed meetings attended.

However, such days generally don't last long.

Not because of new cases, but due to outstanding cases, support for various district and county Criminal Investigation Teams is needed.

Recently, Crime Scene Investigation received a technical support request from the High-tech Zone's Criminal Investigation Team.
